Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have
hyperpigmentation around mouth and it is due to excessive melanin formation..
It can occur due to a number of causes like excess sun exposure, side effects of any skin cosmetic, hormonal imbalances, malnutrition etc..
I would suggest you to take topical
depigmentation treatments like washing your face with
salicylic acid and
glycolic acid containing facewash..
You can apply creams containing Kojic acid, glycolic acid and arbutin..
You can also apply Azelic acid creams..
Apply Vitamin E and C containing creams..
You can also take Vitamin C supplements..
Limit sun exposure and always apply sunscreen lotion when exposed to sun..
You can also exfoliate your kin twice a week..
In case if still there is no improvement you can go for treatments like Chemical peeling, Photofacial and
Microdermabrasion..
Hope this information helps..
Thanks and regards.
